Moreover, we examined two crucial hyper-parameters regarding their impacts on the quality of the style transfer
based on our proposed criterion. The penalty factor \(\alpha \)  over content deviation affects how much content
is preserved in the transferred data. The higher the value, the more content preserved.
Meanwhile, the amount of style transferred will be negatively affected.
The trade-off is accurately depicted by the prediction accuracy change on style and content in the transferred data.
To some extend, it confirms a dependency relation between the content and style.
It indicates that the acoustic content and style are not as separable as in the visual applications[1]}.
